Useful for animating parameter changes. Not meant to be displayed. Instead the position encodes some number, often one which another animation or continual_animation uses for its update function, and by treating it as a mobject it can still be animated and manipulated just like anything else. This value changes continuously when animated using the :attr:`animate` syntax.
